McKenzie Elliott was fatally shot when she was caught in the crossfire of a drive-by shooting. Officials said a stray bullet hit her while she stood on the porch of a house on Old York Road in north Baltimore on Aug. 1.

Officers arrested a man they believed was the shooter at the time, but after the State's Attorney's Office started asking for more information to file charges, the case shifted.

When the reward fund was announced on May 11, Baltimore City State's Attorney Marilyn Mosby said, "We cannot get justice unless the witnesses step up."

Anyone with information about the case is urged to call homicide detectives at 410-396-2100.

"I don't want to hear about the code of the streets or the stop snitchin' mentality because that's the mentality that we have got to change. There are gray areas in almost every situation we face in life, but one thing is clear: The murder of a 3-year-old girl is black and white," Mosby said.

To contribute to the Metro Crime Stoppers reward fund, make a check payable to Metro Crime Stoppers and write "McKenzie Elliott" on the memo line. Any amount given will go to the fund.
